INSTRUMENT FR TURNING TLT'F LEAVES OF lvTUSl-'MBOOTKS. @ce

Specification of Letters; Patent No.

.To all whom it may concern.'

llc it known that l. (Wanze ll. 'rl`1n.\Ynn,oi" l'oaton. in the county ol buiiolltV and State ol Maasaehus'et have invented a new and Improved Music-Leal" llolder and Turner; and l do hereby declare that thc following in a t'nll and exact deacription thereof, refer ence being' had to the accompanying drawinga, makingpart ot' this :niecihcation.l1`igure l being a tront elevation ot' the instru ment; Fig. 2, a plan thereof; Fig. 3, a Similar view thereof, with a portion of the base removed to show the interior arrangement; Fig'. 11, a crosasection thereof in the plane indicated by the line a? .13, Fig'. 1.

Like letteraI designate correapoiiding partal in all the figures.

My improvement may be made as a portable instrument applic; ble to the musicdesk ot any piano, organ, meltiideon or other similar musical inatrument; or it may be made as a part ot the music-desk, or rack, iteelt'.

A. base A, is provided, to the rear of which iS Secured a back l, which may be in the form of an upright or Slightly leaning standard, Since the usual music-rack will assist in Saistainingthe music-lcavt-e. Thin bacl is ot suflicient height to reach above the music-leaves, when they are placed against it. Clamp-jawfs C, l), are Secured in front of the back B, one being immovable and the other movable to and from its cempanion, toward which it is moved and tightened by an eccentric button I, and from which it ia automatically Separated by elastic cords a, a, (Fig. 4,) passing through said clamp-jaw and the back B, or by any equivalent means.

In the top of the back B, is a. slot, or notch, Z), for the reception of Small cords E, E. Theae corda may be of catgut or other suitable material. They are arranged in pairs, and to the upper end of each pair is secured a small knob c, for holding said cords in the notch 7J, which thus becomes the center of motion .tor said cords, as hereinafter set forth. To the lower end of each pair of cords is Secured a ring7 or thimble, rl, which slides on a` curved rod or way,

F. This rod is nearly or quite a half a` circle in extent, and is concentric with the l notch t), where the upper ends of the cords l E, E, are attached, so that when said cords are carried around (as presently to be det 22,690. dated January' 18, 1859.

aut'licient number ot times, to take up their whole length. When thus arranged the elastic corda` hayea 'tree movement which allows` them to Stretch or contract` without nluclx lFriction. The number olE pairs ot cordy C, 1C. thnnblea 7, and elaat'ic cordal (il, (l. Should be ,antlicient to receive as many leaves ot music ati once aa may be tound in any one piece to be played.

vinstead ot the elaetic cord.--y (l, (l, any eqniralcnt may be used which will aecomplieh a like, reanlt; aa, for inatancc, inelaetic corda windingaronnd drums int-losing' coiled springe, Similar to the drum incloaing` the mainsprinfag' ot a watch. i

At the right-hand end` of the base` A, is Situated an eseapement catch lli, Secured to a horizontal aXiH which turns in a Suitable bearing` in said base. Thia` catch has two pointe o, and p, extendinginward so as to receive the rod, or way, F, between them, as Shown moet clearly in Fig. 1; but not too tar to prevent their being' disengaged from the` embrace oi the rod by a slight presaure downward. The two points are not Situated in the santo perpendicular plane, but in planesl autiit'fieutly Separated to receive one of the thiinbles d, between them; so that, when the upper or `front, point y), rests againati they front aide. of one thimble, the lower, or rear point o, will be between the front thilnble and the next succeedingthinlblc. And the points are also situated vertically apart not sutliciently to allow the escape ot a t'himble between them, till they are raised Somewhat by the hand ot thc player. The upper point j), ia pressed and held down in contact with the rod F (as Shown in Fig. 1,), by a spring mi, acting on the end of the aait: 1; or by any equivalent means. The campement-catch is actuated by means; of an arm a, which is touched by the player.

The action oit the instrument is as fol- Iowa; Vll' the loaves to he toructl are those ol` a hooli1 thtl hoolty iu merely placotl against thc latch' l; lust il thc leaves are thoHc olf alwctauuaic1 the hacha ol' tho leaves are plat-ml between the clai1i| -jaws (it, l), and wcllrml thon-in hy lucana ot the eccentric I. ltlaffh leal' to luc tlnuotl7 in the pcifiorl'iiance of a picco. la thcu placetl respectively hetwccn a pair ol' the coitlS ll, ltl, and the upper culle, ot' aaitl corda are all placed in the notch '/n at tho top of thc back. When they are thus arranged,y the cacapeinent-catch H, iay Huapi-ung lronl the` i'ocl il?, by pi'csaiug it downward with the hanfl. Then the thimbles (.7. t?, are, all together, brought around 'from the left-hantl cnil of the hasta to the opposite end, and the cscapelnent catch again malle to Stritle the iotl`y thereby hohlingthe corls and the music-loaves; at` the right-hand of the instrument. Then, at the moment of coinpletingI one page of the music by merelyY slightly touching the end of the arin n, So as to move it inward, (which can be (lone in a moment anfl without scarcely interfering with the perfornuince of a piece) the upper point y), of the catch, is i'rectl from thc front thinible` which iinniecliatelyr escapes; when the corel G, carries it instantlyr around to the left of the instrument7 bearing` the leaf with it. At the same time that the upper point of the eecapenient catch is rising', to free the front thinible, the

lower point tluireo'l? rises in front ot the Sactotaling thinllnlla alul hohla it,` till` the Spring` mi l'oi'ccs hach' the front'y point so as to receivc the thinible as before, and ready for Setting' .i'cc the secontl lea't; and so on till all are Het free. In this manner, any inunbci ot" leaves may be turned, one by one, by siinplty tonchingn the arm n.

'hat I claim as in y invention and desire to Secure, by Letters Patent, is-

1. The double holding),` cords E, E, E, elaS- tic spi-inging cords G, G, Gr, or their equivalents, back ll, provided with clamps C, D, and notch or catch Z, and the curved, concentric rod, or way, F, arrai'iged and operating;` in connection with and in relation to each other sulistantially in the manner and tot' the purpose hei-ein specified.

2. I also claim the escapelnent-catch H, constructed, arranged and operating in con nection with the curved rod F, and thimbles of the holdingcords E, E, E, Substantially as described. v

ln Witness that the above is a true Specification of my improved instrument for turning music leaves and book leaves, I here unto set my hanfl this third (lay of December, 1858.
